Innovative technique to reconstruct two branches of the right hepatic artery in living donor liver transplantation.
Hepatic arterial thrombosis is a critical complication in living donor liver transplantation (LDLT). Two separate branches of the right hepatic artery (RHA) are sometimes observed and addressed by anastomosis of the larger branch first, then checking backflow from the smaller branch. If not good, the smaller branch must be reconstructed. We used the cystic artery as a conduit for the reconstruction. Meticulous dissection was performed to identify all branches of the hepatic artery in the donor operation. The length of cystic artery preserved was as long as possible. The cystic arterial stump was anastomosed to the stump of the posterior branch the of RHA under microscopic guidance on the back table. Patency was checked through the stump of the anterior branch of the RHA. With this technique, only one orifice, the stump of right anterior hepatic artery, was used for hepatic artery reconstruction. We have performed this technique in two patients. Both had good arterial flow after living donor liver transplantation. This innovative technique is easy and safe, and requires only one anastomosis, which, in theory, decreases the adds of developing hepatic arterial thrombosis.
